How large should I make root, home, and swap partitions?

When I'm repartitioning my hard disk, how big should the root partition be for flawless functioning?

Even after 6-8 months after installing (v. 10.10), system files on the root partition occupy just 5.7 Gb.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

@belacqua If it is a duplicate question, sorry, I didn't find it before :). Yet, I think it is important question for users who want to free up HDD space :) – Vincenzo Oct 21 '11 at 20:11
Oh, no problem if it's a duplicate. It's good to point other people at all the answers. If there are better answers that show up here, those can be merged (and I upvoted this as well, since I agree it's a good question). – belacqua Oct 21 '11 at 20:20

It depends on what you do with your computer. When you install software, it will be installed in the root partition. It's a very personal thing. For example, I use about 15gb. If you can, with the hard disks that we have today, I suggest you to create a partition about 20gb for your root.

Thanks for an answer. I am using my laptop for daily tasks at university. Mostly for writing, some calculus (Calc), e-mailing. Sometimes I am editing video, RAW photos, video converting, and DVD burning. Most of my tasks (98%) I do in Ubuntu (now 10.10 and 11.10). – Vincenzo Oct 20 '11 at 22:06
I think 15 Gb will be enough for now :). – Vincenzo Oct 21 '11 at 19:10

To continue with eNry's answer, in my case I'm using 60Gb. I know that is A LOT, but I tend to install a lot of software, including tools for development, audio editing and academic work. Last time I had a root part with 40Gb that got almost full... and my data was in other partition!

I use 15gb for my root partition, and 2.8gb for swap space, it is entirely up to you though and as mentioned above, a, very personal, taste....

Thank you for recommendations. I use the same partitioning except 4 Gb Swap space (for eventual system hybernation. I didn't try for 11.10 :) ) – Vincenzo Oct 21 '11 at 20:35
